Abstract
A fan which can be mounted in a window opening without using any tools, mounting hardware or special brackets or used as a floor fan includes a pair of panel sections which are interconnected by a pair of hinge joints for pivotal movement relative to each other from a fully open position to a folded position. One of the hinge joints includes a mechanism for automatically snap-locking the two panel sections when they are at the fully open position at an angle of about 120 degrees. A pair of adjustable and lockable side extensions are provided, one attached to and extending out from each panel section. A fan unit which includes a motor driven fan is pivotally attached to the panel sections for rotational movement relative thereto.
